There are three Loadable Storage Subsystems (LSS) modules: ZLSS.NSS, CDHFS.NSS, CD9660.NSS, and DOSFAT.NSS. The ZLSS module provides access to logical volumes created by the user. The CD9660 module allows access to CD ROM drives as NSS volumes. The DOS FAT module allows access to FAT 16 and FAT 12 drives.
When NSS recognizes a CD ROM, it creates a Read-only logical volume for that CD ROM. This is done automatically when you load the CDROM.NLM. However, this volume is not added to NDS.
The new CDROM.NLM loads the CD9660.NSS and CDHFS.NSS modules. The CD9660.NSS module loads the ISO966, CDHFS, and Macintosh Hierarchical File System (HFS) file formats. Dual formatted CDs are mounted as two separate volumes. This means both Macintosh and Windows clients will see the same CD ROM volumes with two different layouts.
The CD9660.NSS module makes the contents of the standard ISO9660 CDROM available as a Read-Only logical volume. If the CDROM is in the drive when CD9660 loads, it will mount as a logical volume immediately.
The volume name displayed by the NetWare volumes command is the CD-ROM volume label if one exists. Otherwise, NSS generates a volume name in this form: CDXXXXXX (where X is a number). This volume functions the same as any other NetWare volume, except that it is Read-Only.
To load both the CD9660 and CDHFS modules, enter the following at the server console:
load cd-rom.nlm
To load CD9660.NSS alone, enter the following at the server console:
load cd9660.nss
To load CDHFS.NSS alone, enter the following at the server console:
load cdhfs.nss
To unload CD9660.NSS, enter the following at the server console:
unload cd9660.nss
To unload CDHFS.NSS, enter the following at the server console:
unload cdhfs.nss
The CD ROM unload process dismounts the volumes.
Digital Versatile Disc (DVD), the newer optical storage technology, requires Universal Disc Format (UDF) support. DVD provides access time similar to CD-ROMs, has a bigger storage space, and records data in a universal format---meaning, you no longer need a plethora of different drivers to access the data.
To mount a DVD as a logical volume, you need the following:
At the server console, enter
LOAD UDF.NSS
To dismount a DVD, at the server console enter
UNLOAD UDF.NSS
After you load the DOSFAT.NSS module, any DOS FAT partitions are dynamically made available as logical volumes. The volume name displayed by the NetWare volumes command is DOSFAT_X, where X is the drive letter, for example DOSFAT_C.
The following are some benefits of the DOSFAT.NSS module:
Long filenames (such as DOS filenames for file systems such as OS/2). This uses the Windows* 95/98 method for placing long names onto a DOS FAT partition.
NetWare trustee rights. Only users with supervisor rights can access the volume.
NetWare utilities. Any client or server utility that accesses or manages NetWare volumes can do the same with DOS FAT partitions.
MAP command. NetWare clients can map to the volume and use it as any other NetWare mapping.
Local partition. Allows access to the local partition.
